Human visual mechanisms (HVMs) can quickly localize the most salient object in natural images, but it is ineffective at localizing tumors in ultrasound breast images. In this paper, we research the characteristics of tumors, develop a classic HVM and propose a novel auto-localization method. Comparing to surrounding areas, tumors have higher global and local contrast. In this method, intensity,...

This article argues that the practical jokes running throughout Wilson’s novel Our Nig; or Sketches from the Life of a Free Black (1859) are evidence of a deliberate and sophisticated comic strategy that exploits the spectacular body’s potential for subversive performance and works against thealienating conditions of social and political marginalisation experienced by African Americans in<l...

The present study considers a fuzzy natural color system (NCS) in which triangular pyramid membership functions are constructed on the NCS color triangle. This system can process a fuzzy input to an NCS and output a center of gravity of three weights associated with respective grades. Triangular membership functions are applied to the hue angle, and triangular pyramid membership functions are a...
